Rattana's place is a lovely oasis from the hectic streets of Bangkok. We stayed with her for 5 nights. Spotless and comfortable room and beds, access to fantastic facilities, and a host always willing to support your needs around the city. She was even our essential guide and advocate during a visit to Chatuchak market!
Unless you need to be in the very center of Bangkok (which are still easily accessible by several means of public transport) we highly recommend staying with Rattana!
